ruby-on-rails - Rails 3.1 + Heroku = worker 崩溃

Question

所以，我刚刚建立了一个全新的 Rails 3.1.1 应用程序 (Ruby 1.8.7)。

在那里放置一些脚手架，安装 Authlogic，并创建一个新的 Heroku 应用程序。将其推送到 Heroku 并迁移数据库。

一切都很好。我可以使用 Authlogic 创建新的用户帐户，并在 Heroku 上的模型中创建新记录。

不过，有趣的是。如果我将“worker dynos”从零增加到任何值，heroku 日志会显示那些试图启动的 worker 但他们崩溃了。

但是，我没有安装 Delayed Job。并且从未向此应用引入 Delayed Job

除了 Twilio 或任何高级代码之外，我还没有介绍任何“高级”gem。它只是带有 authlogic 的新 Rails 应用程序。也没有新的抽成任务。

另一个注意事项:在我的本地开发机器上，我尝试在不同的应用程序上安装 Delayed Job，但失败了。延迟工作的“幽灵”是否会困扰这个新应用？

谢谢!

下面的代码......

在我将 Web worker 从 0 --> 2 增加后，Heroku 记录。

Answer 1

Worker dynos 专门处理延迟作业任务。

如果您没有安装 Delayed Job，那么您不应该扩展您的工作人员数量(这是处理 DJ 工作的原因)。

如果你想扩展你的网络测功机，那么只需扩展 web=2 或任何你想要的。

我猜你的错误是因为你新晋级的 DJ worker 找不到任何工作要做，所以它出错了。

缩放 worker=0 并查看是否修复了它。

如果您想扩展网络测功机以获得更好的性能，网络就是您要找的。
